Paul Samuelson made a series of important contributions to population theory for humans and other species, evolutionary theory, and the theory of age structured life cycles in economic equilibrium and growth. The work is highly abstract but much of it was intended to illuminate issues of...

The demographic transition can affect the equilibrium real interest rate through three channels. An increase in longevity - or expectations thereof - puts downward pressure on the real interest rate, as agents build up their savings in anticipation of a longer retirement period. A reduction in...

This working paper provides an overview of demographic trends that are upending the Eastern and Southern Africa (ESA) region and the potential to capitalize on the demographic dividend. The demographic dividend is the time-bound opportunity to catalyze economic growth and poverty reduction as...

Is Japan's aging and, more recently, declining population hampering growth and reflation efforts? Exploiting demographic and economic variation in prefectural data between 1990 and 2007, we find that aging of the working age population has had a significant negative impact on total factor...

Population growth has two potentially counteracting effects on pollution emissions:(i) more people implies more production and thereby more emissions, and (ii) more people implies a larger research capacity which might reduce the emission intensity of production, depending on the direction of...

The nexus of population dynamics and environmental degradation has been discussed widely in the extant literature. Most related studies have utilized carbon emission as a proxy of environmental quality. However, carbon emission does not capture the multidimensional nature of environmental...

Economists are divided about population growth: the pessimism of neo-Malthusians contrasts strongly with the optimism of cornucopians. Despite their differences, both schools of thought reject economic orthodoxy and prefer evolutionary forms of theory. Their interpretations of evolution are...

The nexus of population dynamics and environmental degradation has been discussed widely in the extant literature. Most related studies have utilized carbon emission as a proxy of environmental quality. However, carbon emission does not capture the multidimensional nature of environmental...

This paper empirically examines the effect of population growth on real interest rates. Although this effect is well founded in macroeconomic theory, the corresponding empirical results have been rather tenuous. Demographic interest rate theories are typically based on long-term relationships...

Post Keynesian stagnation theory argues that slower population growth dampens consumption and investment. A New Keynesian OLG model derives an unemployment equilibrium due to a negative natural rate in a three-generations credit contract framework. Besides deleveraging or rising inequality, also...
